RESUMO
Avoidable readmissions after bariatric surgery are a major burden on the healthcare systems. Rates of readmission after bariatric surgery have ranged from 1% up to 20%, but the factors that predict readmission have not been well studied. The objective of this study was to determine readmission rates following bariatric surgery and identify factors that contribute to early (within 90 days of surgery) and late readmission. A retrospective cohort study of 736 patients undergoing either Laparoscopic Sleeve Gastrectomy or Laparoscopic Roux-en-Y Gastric Bypass in Jordan University Hospital from 2016 to 2019. Demographic characteristics, co-morbidities, and readmissions were extracted from their medical records and analyzed. Multivariable logistic regression analysis was performed to determine which factors predict readmission. A total of 736 patients had bariatric surgery (Laparoscopic Sleeve Gastrectomy 89% vs Laparoscopic Roux-en-Y Gastric Bypass 11%) during the study period. Thirty-day readmission rate was 6.62% and an overall readmission rate of 23.23%. Common reasons for early readmission (within 90 days of surgery) were nausea, vomiting, and dehydration. Late readmissions were mainly caused by gallbladder stones. Three risk factors were identified that independently predicted readmission: the type of procedure being performed (P-valueâ =â .003, odds ratio [OR] 2.14, 95% confidence interval [CI] 1.32-3.49), depression (P-valueâ =â .028, OR 6.49, 95% CI 1.18-52.9) and preoperative body mass index (P-valueâ =â .011, OR 1.03, 95% CI 1.01-1.05). Several factors were identified that cause patients to represent and subsequently admitted into hospitals. Early readmission was usually due to nausea, vomiting, and dehydration, whereas late admissions were mostly due to biliary complications. Preoperative body mass index and depression were independent risk factors for readmission.

BACKGROUND: The incidence of dysnatremia in children with acute gastritis/gastroenteritis varies, and factors associated with either dysnatremia or hyponatremia at presentation have not been identified clearly. METHODS: This retrospective study included patients aged 1 month to 18 years hospitalized for community-acquired acute gastritis/gastroenteritis from January to October 2016. Factors associated with dysnatremia at presentation were identified using multivariable analysis. RESULTS: Among the 304 children included, the median age was 2.2 (1.0, 4.2) years. The incidence of dysnatremia at presentation was 17.1% (hyponatremia 15.8%; hypernatremia 1.3%). Patients who had moderate (p = 0.03) and severe dehydration (p = 0.04) and presented with vomiting and diarrhea simultaneously (p = 0.03) were associated with dysnatremia at presentation. Patients presented with vomiting and diarrhea simultaneously was associated with hyponatremia at presentation (p = 0.02). CONCLUSIONS: Dysnatremia was common in children with acute gastritis/gastroenteritis. Moderate to severe dehydration and the presence of vomiting and diarrhea simultanously were significantly associated with dysnatremia at presentation. Furthermore, presenting with vomiting and diarrhea silmutaneously was associated with hyponatremia at presentation. Serum electrolytes should be monitored in patients with those conditions.

Diabetes, especially type 2 diabetes (T2D), poses an unprecedented challenge to global public health. Hydration status also plays a fundamental role in human health, especially in people with T2D, which is often overlooked. This study aimed to explore the longitudinal associations between hydration status and the risk of T2D among the Chinese population. This study used data from the large community-based Kailuan cohort, which included adults who attended physical examinations from 2006 to 2007 and were followed until 2020. A total of 71,526 participants who eventually met the standards were divided into five hydration-status groups based on their levels of urine specific gravity (USG). Multivariable and time-dependent Cox proportional hazards models were employed to evaluate the associations of baseline and time-dependent hydration status with T2D incidence. Restricted cubic splines (RCS) analysis was used to examine the dose-response relationship between hydration status and the risk of T2D. Over a median 12.22-year follow-up time, 11,804 of the participants developed T2D. Compared with the optimal hydration-status group, participants with dehydration and severe dehydration had a significantly increased risk of diabetes, with adjusted hazard ratios (95% CI) of 1.30 (1.04-1.63) and 1.38 (1.10-1.74). Time-dependent analyses further confirmed the adverse effects of impending dehydration, dehydration, and severe dehydration on T2D incidence by 16%, 26%, and 33% compared with the reference group. Inadequate hydration is significantly associated with increased risks of T2D among Chinese adults. Our findings provided new epidemiological evidence and highlighted the potential role of adequate hydration status in the early prevention of T2D development.

BACKGROUND: Pregnancy-related kidney injury contributes to a high burden of acute kidney injury in low-resource settings and causes maternal and perinatal morbidity and mortality. Few studies have examined the impact of acute kidney injury in resource-limited countries, with very limited research on pregnancy-specific disorders in Ethiopia. This study aimed to determine the characteristics of pregnancy-related acute kidney injury, outcomes and associated factors. METHODS: A retrospective study was conducted to evaluate the clinical profile and maternal-fetal outcome of pregnancy-related acute kidney injury at Ayder Comprehensive Specialized Hospital in Tigray, Ethiopia, from January 1, 2017, to December 31, 2021. Maternal and fetal outcomes were analyzed using descriptive statistics. Multivariate logistic regression was used to determine the association between the dependent and independent variables. RESULTS: Of 27,350 mothers who delivered at Ayder Comprehensive Specialized Hospital between January 1, 2017, and December 31, 2021, a total of 187 women developed pregnancy-related acute kidney injury, a prevalence rate of 68 per 100,000 births. Preeclampsia, sepsis and pre-renal causes due to dehydration and hemorrhage were the most common causes of pregnancy-related acute kidney injury in this study. Hemodialysis was needed in 8.6% (n = 16) of patients. Of the 187 pregnancy-related acute kidney injuries, 143 (76.5%) recovered completely and 30 (16%) partially. The mortality rate was 7.5%. Preexisting chronic kidney disease (AOR = 30.13; 95% CI: 2.92, 310.84), use of vasoactive agents (AOR = 5.77; 95% CI: 1.47, 22.67), increase in creatinine per unit (AOR = 1.65; 95% CI: 1.11, 2.45) and complications related to acute kidney injury (AOR = 5.26; 95% CI: 1.73, 16.00) were determinants of the composite endpoints (partial renal recovery and death). CONCLUSIONS: This study emphasizes acute kidney injury in resource-limited settings is a significant cause of maternal and fetal morbidity and mortality. The vast majority of patients with pregnancy-related acute kidney injury recovered completely from kidney injury. The main causes of pregnancy-related acute kidney injury were preeclampsia, sepsis and pre-renal associated with hemorrhage and dehydration. Preexisting renal disease, use of vasopressors, increase in creatinine per unit and complications associated with acute kidney injury were determining factors for concomitant fetomaternal mortality. Appropriate preventive strategies during prenatal care and prompt treatment are needed for pregnancy-related acute kidney injury.

BACKGROUND: Rotavirus has a significant morbidity and mortality in children under two years. The burden of rotavirus diarrhea 4 years post introduction of rotavirus vaccine in Uganda is not well established. This study aimed to determine the prevalence, severity of dehydration and factors associated with rotavirus diarrhea among children aged 3 to 24 months after the introduction of the vaccine at Fort Portal Regional Referral hospital. METHODS: This was a cross-sectional hospital-based study in which children with acute watery diarrhea were included. A rectal tube was used to collect a stool sample for those unable to provide samples. Stool was tested for rotavirus using rapid immunochromatographic assay. Data was analysed using SPSS version 22 with logistic regression done to determine the factors. RESULTS: Out of 268 children with acute watery diarrhea, 133 (49.6%) were females. Rotavirus test was positive in 42 (15.7%), majority of whom had some dehydration 28(66.7%). The factors that were independently associated with rotavirus diarrhea were; age < 12 months (AOR = 8.87, P = 0.014), male gender (AOR = 0.08, P = 0.001), coming from a home with another person with diarrhea (AOR = 17.82, P = 0.001) or a home where the water source was a well (AOR = 50.17, P = 0.002). CONCLUSION: The prevalence of rotavirus diarrhea was three times less in the post rotavirus vaccination period compared to pre-rota vaccination period. Majority of the participants with rotavirus diarrhea had some dehydration. There is need for provision of safe water sources to all homes. Surveillance to determine the cause of the non rota diarrhea should be done.

BACKGROUND: Readmission rates following ileostomy formation are high. Dehydration and consecutive renal failure are common causes of readmission, potentially pronounced by drugs affecting the homeostasis. The aim of the study was to assess the risk of dehydration after ileostomy formation in patients treated with angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB) or diuretics. METHOD: This nationwide population-based cohort study used data derived from the Colorectal Cancer Data Base of several Swedish healthcare registers. The study included all patients operated on with elective anterior resection and temporary ileostomy for rectal cancer clinically staged I-III in Sweden in 2007-2016. Exposure was at least two dispensations of ACEI, ARB or diuretics within 1 year prior to surgery. Outcome was 90-day readmission due to dehydration including acute renal failure. RESULTS: In total, 3252 patients were included with 1173 (36.1%) exposed to ACEI, ARB or diuretics. The cumulative incidence for 90-day readmission due to dehydration was 29.0% (151 of 520) for exposed versus 13.8% (98 of 712) for unexposed. The proportion of readmissions due to any reason was 44.3% (520 of 1173) for exposed compared to 34.2% (712 of 2079) for unexposed. The incidence rate ratio for readmission due to dehydration was 2.83 (95% c.i. 2.21 to 3.63, P < 0.001). The hazard rate ratio was 2.45 (95% c.i. 1.83 to 3.27, P < 0.001) after adjusting for age, gender and comorbidity. CONCLUSION: Medication with ACEI, ARB or diuretics defines a vulnerable patient group with increased risk of readmission due to dehydration after ileostomy formation.

OBJECTIVE: Farmworkers are at increased risk of adverse health outcomes related to occupational heat exposure and inadequate access to water, shade, or rest breaks. Presently, there is a dearth of studies examining the prevalence of dehydration and related factors in U.S. farmworkers. Our objectives were to characterize hydration status during typical workdays and to identify risk factors associated with increased dehydration in migrant farmworkers employed in Florida. METHODS: Urine samples were collected and analyzed for urine specific gravity (USG) 2-3 times per person per day over five days in May 2021 and 2022. Data collection included demographic characteristics, wet-bulb-globe-temperature (WBGT), and information on working conditions (task type, duration, and crop units harvested), fluid intake, clothing worn, and heat safety behaviors. Multivariable mixed regression models were used to evaluate risk factors associated with change in USG levels (continuous) during a work shift. RESULTS: A total of 111 farmworkers participated in this study providing 1020 cumulative USG measurements, of which 96.8% of end-of-shift USG samples were above 1.020 indicating potential dehydration. In multivariable models, dehydration assessed using change in USG levels significantly declined with age (ß = -0.078; 95%CI: 0.150, -0.006) but showed significant increase with body mass index (ß = 0.016; 95%CI: 0.003, 0.028), WGBT (ß = 0.054; 95%CI:0.044, 0.064), mean shift duration, and state of primary residence. We did not find significant associations of dehydration with type of clothing worn, intake of employer-provided water, or crop units harvested during a shift in this sample of farmworkers. CONCLUSION: Our findings underscore the need for additional research to evaluate adverse outcomes related to dehydration and to better understand recovery patterns from chronic dehydration across workweeks and harvest seasons in migrant farmworkers.

OBJECTIVE: Hydration status and water intake are critical to physiological health. Despite a popular narrative that dehydration impairs cognitive performance, results are mixed in the literature. Therefore, we tested how hydration status was associated with cognitive performance in an ad libitum state over the course of 3 months. METHODS: Data come from a short-term longitudinal study among middle-to-older aged US adults (n = 78) measured three times (207 observations). All participants were scheduled for 8:00 a.m. visits for the baseline, two-week, and 3-month examinations where they completed surveys, neuropsychological tests to measure cognitive performance, anthropometrics, and a blood draw for biomarker analysis. Serum osmolality (Sosm) was measured as a biomarker of hydration status using osmometry. Four cognitive performance tasks were assessed, including inhibition, working memory, cognitive flexibility, and sustained attention. RESULTS: Panel random effects linear regressions demonstrate that there was an inverse association between dehydration and sustained attention, whereas there were no significant relationships between dehydration and inhibition, working memory, and cognitive flexibility. Adults who were dehydrated (defined as Sosm >300 mOsm/kg) performed substantially worse (B = 0.65 z-score; SE = 0.28; p = .020) on the sustained attention task than those who were not dehydrated adjusting for time fixed effects, age, body mass index, sex, and educational attainment. CONCLUSION: This short-term longitudinal study found that dehydration was only associated with poorer performance on a cognitive performance task that required sustained attention. Maintaining adequate hydration may be increasingly important for middle-to-older aged adults to ensure proper cognitive function, particularly as water needs increase in future climatic scenarios.

AIMS: Dehydration is one of the common complications of dysphagia and poses significant risks including hospitalization and mortality, but the relationship between dysphagia and dehydration has received little attention. This study aims to determine the prevalence and risk factors for dehydration of patients with dysphagia in eastern China, and to provide reference for early identification and prevention of dehydration. METHODS: A descriptive, cross-sectional design was conducted. Three hundred and thirty-seven (n = 337) patients with dysphagia participated in the study between August and December 2022. Information relating to participants' demographic variables, nutrition, cognition, functional, hydration status and fluid intake was collected. Univariate analysis was used to examine related impact factors, and then binary logistic regression analysis was conducted to determine reliable impact factors. RESULTS: Among 337 patients with dysphagia, the average age was 63.47 ± 16.96, most participants were male (72.1%) and married (91.7%). The prevalence of dehydration was calculated to be 43.9%, the mean plasma osmolality score was 293.53 mmol/L. Diseases with the highest prevalence were stroke (78.3%), followed by hypertension (63.5%). The risk for dehydration increased with older age, usage of more medicines such as diuretics and beta-blockers, worse functional status and lower fluid intake. CONCLUSION: This study found a high percentage of dehydration in patients with dysphagia. Findings can provide a basis for targeted nursing interventions for clinical prevention and treatment of dehydration.

Pressure ulcers and dehydration are common conditions among residents of long-term care facilities that result in negative health effects. They have been associated with signs of neglect and increased 30-day mortality among LTC residents. However, they are both preventable and with proper care can be effectively managed and treated. We conducted a retrospective cohort study to examine factors associated with pressure ulcers and dehydration among long-term care residents in the province of Ontario, Canada. Results indicated that close to one-fifth of residents were dehydrated (17.3%) or had a pressure ulcer (18.9%) during the study period. Advanced age was significantly associated with the presence of pressure ulcers and dehydration for both men and women. However, men were more likely to present with a pressure ulcer while women were more likely to exhibit symptoms of dehydration. Study findings also demonstrate the presence of both conditions being higher in municipal and not-for-profit homes compared to for-profit homes. The significant differences observed in relation to home ownership which require further investigation to identify the most relevant factors in explaining these differences. Overall, pressure ulcers and dehydration are preventable conditions that warrant attention from policymakers to ensure quality of care and resident safety are prioritized.

OBJECTIVES: Adequate hydration is essential for the maintenance of physiological functions. Older adults may not be able to maintain adequate hydration, which is often not recognized. Our aim was to investigate the prevalence, risk factors and clinical implications of dehydration in older adults. METHODS: This cross-sectional study included 964 older adults in one geriatric outpatient clinic in Turkey. Dehydration was defined as a calculated [1,86 × (Na+K)+1,15×glucose+urea +14] plasma osmolarity of ≥ 295 mOsm/L. Clinical characteristics and measures of comprehensive geriatric assessments of patients with dehydration and normohydration were compared. Predictors of dehydration were assessed using logistic regression analysis. RESULTS: Mean age was 79.9 ± 7.7 years, (71.7% female). The prevalence of dehydration was 31%. Female patients, diabetes mellitus (DM), chronic renal failure (CKD), a higher risk of falling (based on Timed Up and Go test), probable sarcopenia, dependence based on basic and instrumental daily living activities (BADL and IADL) were more common in the dehydrated group (p < 0.05). After adjusting for age and gender, dependency on BADL and IADL, the risk of falling were still higher in the dehydrated group (p < 0.05). There were significant relationships between dehydration and risk of falling (OR 1.38, 95% CI 1.00-1.90; p < 0.05), after adjustment for age, gender, DM, CKD. CONCLUSION: Dehydration is common among older adults and is associated with a dependency, probable sarcopenia, and an increased risk of falling. Screening for dehydration and taking preventive measures may be beneficial in avoiding the negative consequences associated with dehydration.

OBJECTIVES: The aim of this study was to evaluate the clinical profile and outcome of young infants presenting to the pediatric emergency department with hypernatremic dehydration. METHODS: A prospective observational study was conducted at a tertiary care teaching hospital over a period of 18 months. All outborn sick young infants aged 2 months or younger who presented to the emergency department with symptoms and signs of possible sepsis and/or dehydration were screened, and those with hypernatremia were enrolled in the study. Those infants born at less than 37 weeks of gestation and gross congenital anomaly were excluded. Hypernatremic dehydration was defined as serum sodium levels (Se Na+)higher than 145 mEq/L. Variables used in the study were defined as per standard definitions. Acute kidney injury was defined and staged using serum creatinine as per modified neonatal Kidney Disease Improving Global Outcome guidelines. Clinical presentation, laboratory parameters, and comorbidities were compared among outcome groups (survived and died). RESULTS: Of 1124 outborn young infants who met the eligibility criteria for screening, 63 were diagnosed to have hypernatremic dehydration and 55 were enrolled. The hospital-based period prevalence of hypernatremic dehydration in young infants was 4.89%. The median age of presentation was 17 days (10-30). Male-to-female ratio was 1.1:1. Seventy-three percent were first in birth order. Feeding pattern showed 61.8%, 30.9%, and 7.3% of infants were exclusively breastfed, top fed, and mixed fed, respectively. The median serum sodium at the time of admission was 160 (153.5-167) mg/dL. Three (5.5%) infants had mild, 39 (70.9%) had moderate, and 13 (23.6%) had severe hypernatremic dehydration. There was statistically significant correlation between median platelet count with severity of hypernatremic dehydration. The mean time taken to correct serum sodium level was 3.30 ± 1.60 days. The case fatality rate was 41.8%. Those who died had statistically more severe hypernatremic dehydration, acute kidney injury, sepsis, and need for ventilation. CONCLUSIONS: Acute kidney injury stage 3, shock, and need for ventilation are associated with poor outcome in infants with hypernatremic dehydration.

BACKGROUND: Paediatric kidney transplant recipients may be at a particular risk of dehydration due to poor kidney concentrating capacity and illness associated with poor fluid intake or losses. In this population, creatinine rise may be more likely with relatively mild dehydration, which may trigger hospital admission. This study describes hospital admissions in the first 12 months after transplantation with diagnosis of graft dysfunction associated with dehydration due to illness or poor fluid intake. We assess risk factors for these admissions. METHODS: Data was extracted from medical records of patients transplanted in two tertiary children hospitals. Following descriptive analysis, multiple failure regression analyses were used to identify factors associated with admission for acute kidney allograft dysfunction associated with dehydration. RESULTS: Of 92 children, 42% had at least 1 dehydration admission in the 12 months following transplantation. Almost half of the dehydration admissions were due to poor fluid intake, which accounted for 1/5 of all unplanned hospital admissions. Target fluid intake at first discharge of > 100 ml/kg/day was associated with dehydration admissions of all types (hazard ratio (HR) 2.04 (95% CI 1.13-3.68)). Teen age was associated with poor fluid intake dehydration admissions (HR 4.87 (95% CI 1.19-19.86)), which were more frequent in mid-summer. Use of enteric feeding tube, which correlated with age under 4, associated with contributing illness dehydration admissions (HR 2.18 (95% CI 1.08-4.41)). CONCLUSIONS: Dehydration admissions in the 12 months following childhood kidney transplantation are common. Highlighted admission risk factors should prompt further study into optimal fluid intake prescription and hydration advice given to children, teenagers, and their carers following kidney transplantation. Use of an enteric feeding tube may not protect patients from admission with dehydration associated with contributing illness.

Children with malnutrition present with aberrant laboratory parameters. This study aimed to identify high-risk diarrheal children with varied nutritional status. The data were obtained from the electronic database of Dhaka Hospital, International Centre for Diarrhoeal Disease Research, Bangladesh from 2019 to 2021. Among 1,068 children under 5 years of age with diarrhea, 177 (14%) had severe acute malnutrition (SAM; weight-for-length/height Z score < -3), 239 children (17%) had severe stunting (SS; length/height-for-age Z score < -3), and 652 did not have malnutrition (weight-for-length/height and weight-for-age and length/height-for-age Z score > -2). We independently assessed the relationship of nutritional profiles with each clinical and laboratory parameter. After adjustment for age and sex in the multiple regression model, hyponatremia (adjusted odds ratio [aOR] = 2.37 [95% CI: 1.52-3.68]; P < 0.001) and dehydration (aOR = 2.42 [95% CI: 1.67-3.52]; P < 0.001) were independently associated with SAM compared with children without malnutrition. In comparison to non-malnutrition, SS was less likely to be associated with acute watery diarrhea (aOR = 0.66 [95% CI: 0.47-0.92]; P = 0.014) but was significantly associated with anemia (aOR = 2.18 [95% CI: 1.57-3.02]; P < 0.001) and thrombocytosis (aOR = 2.43 [95% CI: 1.78-3.32]; P < 0.001). The presence of hypernatremia was substantially lower in children with SAM (aOR = 0.38 [95% CI: 0.22-0.65]; P < 0.001) or SS (aOR = 0.56 [95% CI: 0.35-0.88]; P = 0.012) than in children without malnutrition. Severe stunting was less likely to be associated with dehydration (aOR = 0.44 [95% CI: 0.29-0.67]; P < 0.001) in contrast to SAM. Therefore, children hospitalized with diarrhea may have different clinical and laboratory manifestations depending on their nutritional status and may require differential treatment.

BACKGROUND AND AIMS: Malnutrition and low-intake dehydration both increase complications and mortality in hospitalized older medical patients. Nutrition Impact Symptoms (NIS) are barriers for obtaining an adequate nutritional intake and possibly adequate fluid. Therefore, we aimed to assess the prevalence of low-intake dehydration and specific NIS, and the relation between low-intake dehydration and specific NIS. METHODS: A retrospective cohort study among older patients (≥65 years) from the Medical Department at Herlev-Gentofte Hospital and referred to a clinical dietitian. Data about sex, age, BMI, prevalence of nutritional risk (NRS-2002), low-intake dehydration (calculated osmolarity >295 mmol/L), and NIS (the EATEN-questionnaire, comprising 16 NIS-questions and whether these were respectively present and limiting nutritional intake) were collected from the hospital records. RESULTS: We included 99 patients (61% women), mean age 81 years (±7.9), median BMI 21.8 kg/m2 (IQR:19.5-25.4). Nutritional risk was found in 74%, and low-intake dehydration in 40% of the included patients. The three most frequent NIS-present were: Early satiety (84%), no appetite (82%), and tiredness (72%). The three most frequent NIS-limiting intake were: No appetite (73%), early satiety (69%), and dry mouth (42%). We found low-intake dehydration to be related to a lower prevalence of the following NIS-present; dry mouth (58% vs.80%, p = 0.0210), and breathlessness (24% vs.49%, p = 0.0179). Among the NIS-limiting intake a lower prevalence of other pains was related to low-intake dehydration (7% vs.29%, p = 0.0233). CONCLUSION: NIS and low-intake dehydration are highly prevalent in older patients. There is limited association between low-intake dehydration and specific NIS.

BACKGROUND AND AIM: There is an overlap between the risk factors causing low intake of water and low intake of nutrients, respectively. This study aims to explore the agreement between the assessment of malnutrition and the outcome of low-intake dehydration in a population of older hospitalized patients. METHODS: Patients ≥65 years old and hospitalized at the geriatric hospital ward were screened for eligibility within 96 h of admission. Dehydration was assessed with the calculated serum osmolarity ≥295 mmol/L (1.86 × (Na+ + K+) + 1.15 × glucose + urea + 14), and (risk of) malnutrition was assessed with NRS-2002 ≥ 3 points, MNA-SF ≤ 7 points, MNA-LF < 17, MUST ≥ 2 points, and GLIM after screening with NRS-2002 and MNA-LF. Follow-up data regarding exercise rehabilitation, readmissions, and mortality was collected 30 days after discharge. Statistics used were the Chi-squared test, Fishers-exact test, and Wilcoxon signed rank test. RESULTS: A total of 114 patients (57% females) were included. Median age 85.5 (IQR 80; 89.25) years. A total of 49 (43%) were dehydrated. Fewer females were dehydrated (F: 42.9% vs. M: 67.7%, p = 0.013). The patients with osmolarity ≥295 mmol/L had a higher median weight (68.3 (IQR 58.5; 78.4) vs. 62 (IQR 51.8; 72.1), p = 0.021) and mid-up-arm circumference (27 (IQR 26; 30) vs. 25.5 (IQR 22.9; 28.3), p = 0.004). No significant difference was found in the prevalence of malnutrition between those with or without dehydration (NRS-2002; 70% vs. 81%, p = 0.174; MNA-SF: 23.1 vs. 23.2%, p = 1.0; MNA-LF: 37.1 vs. 30.2%, p = 0.644; MUST: 24.5 vs. 33.8%, p = 0.308; GLIM after screening with NRS-2002: 84.4 vs. 74.5%, p = 0.405, GLIM after screening with MNA-LF: 74.1 vs. 75.6%, p = 0.438). Kappa values varied around 0 and reflected low agreement. There were no differences in the follow-up data, between those who were normohydrated and those who were dehydrated. CONCLUSION: We found low agreement between the assessment of malnutrition and low-intake dehydration in a population of older hospitalized patients. All geriatric patients should therefore be assessed for both conditions.

BACKGROUND: Hydration disturbances are common in old age: the reported prevalence of dehydration in elderly patients ranges from 19% to 89%, depending on the definition and the population in question. However, the clinical assessment of patients' hydration status is difficult. In this review, we discuss the diagnostic value of currently used methods that may or may not be suitable for assessing older patients' hydration status. METHODS: We conducted a selective literature search for relevant studies concerning patients aged 65 and above. Of the 355 articles retrieved by the initial search, a multistep selection process yielded 30 that were suitable for inclusion in this review. RESULTS: 107 different methods for the diagnostic assessment of dehydration in older persons were evaluated on the basis of the reviewed publications. High diagnostic value, especially for the determination of hyperosmolar dehydration, was found for serum osmolality, serum sodium concentration, inferior vena cava ultrasonography, a history (from the patient or another informant) of not drinking between meals, and axillary dryness. On the other hand, a variety of clinical signs such as a positive skin turgor test, sunken eyes, dry mouth, tachycardia, orthostatic dysregulation, and dark urine were found to be of inadequate diagnostic value. CONCLUSION: Only five of the 107 methods considered appear to be suitable for determining that a patient is dehydrated. Thus, the available scientific evidence indicates that all clinicians should critically reconsider their own techniques for assessing hydration status in elderly patients. To optimize the clinical assessment of patients' hydration status, there seems to be a need for the rejection of unsuitable methods in favor of either newly developed criteria or of a combination of the best criteria already in use.

BACKGROUND: This study aimed to describe the clinical characteristics and severity of young infants hospitalized with COVID-19 and study the relationship between breastfeeding and maternal COVID-19 vaccination on the severity of COVID-19. METHODS: A retrospective, observational study was performed among infants aged 6 months and below hospitalized for COVID-19 in a tertiary state hospital in Malaysia between February 1 and April 30, 2022. The primary outcome was "serious disease," defined as pneumonia requiring respiratory support or dehydration with warning signs. Multivariate logistic regression was used to determine independent predictors for serious disease. RESULTS: A total of 102 infants were included in the study; 53.9% were males with a median age of 11 weeks (interquartile range: 5-20 weeks). Sixteen patients (15.7%) had pre-existing comorbidities, including preterm birth. Fever was the most common presenting symptom (82.4%), followed by cough (53.9%), and rhinorrhea (31.4%). Forty-one infants (40.2%) presented with serious disease, warranting either respiratory support or intravenous fluid therapy for dehydration. Recent maternal COVID-19 vaccination was associated with a reduced risk of serious disease on univariate analysis but was not significant after multivariate adjustment (adjusted odds ratio [aOR] 0.39; 95% CI: 0.14-1.11; p = 0.08). Exclusive breastfeeding was protective against serious COVID-19 in young infants, independent of other confounding factors (aOR 0.21, 95% CI: 0.06-0.71; p = 0.01). CONCLUSION: COVID-19 is a serious disease with non-specific clinical manifestations in young infants. Exclusive breastfeeding could play an important protective role.

BACKGROUND & AIMS: Low-intake dehydration amongst older people, caused by insufficient fluid intake, is associated with mortality, multiple long-term health conditions and hospitalisation. The prevalence of low-intake dehydration in older adults, and which groups are most at-risk, is unclear. We conducted a high-quality systematic review and meta-analysis, implementing an innovative methodology, to establish the prevalence of low-intake dehydration in older people (PROSPERO registration: CRD42021241252). METHOD: We systematically searched Medline (Ovid), Cochrane CENTRAL, Embase (Ovid), CINAHL and Proquest from inception until April 2023 and Nutrition and Food Sciences until March 2021. We included studies that assessed hydration status for non-hospitalised participants aged ≥65 years, by directly-measured serum/plasma osmolality, calculated serum/plasma osmolarity and/or 24-h oral fluid intake. Inclusion, data extraction and risk of bias assessment was carried out independently in duplicate. RESULTS: From 11,077 titles and abstracts, we included 61 (22,398 participants), including 44 in quality-effects meta-analysis. Meta-analysis suggested that 24% (95% CI: 0.07, 0.46) of older people were dehydrated (assessed using directly-measured osmolality >300 mOsm/kg, the most reliable measure). Subgroup analyses indicated that both long-term care residents (34%, 95% CI: 0.09, 0.61) and community-dwelling older adults (19%, 95% CI: 0.00, 0.48) were highly likely to be dehydrated. Those with more pre-existing illnesses (37%, 95% CI: 0.14, 0.62) had higher low-intake dehydration prevalence than others (15%, 95% CI: 0.00, 0.43), and there was a non-significant suggestion that those with renal impairment (42%, 95% CI: 0.23, 0.61) were more likely to be dehydrated than others (23%, 95% CI: 0.03, 0.47), but there were no clear differences in prevalence by age, sex, functional, cognitive or diabetic status. GRADE quality of evidence was low as to the exact prevalence due to high levels of heterogeneity between studies. CONCLUSION: Quality-effects meta-analysis estimated that a quarter of non-hospitalised older people were dehydrated. Widely varying prevalence rates in individual studies, from both long-term care and community groups, highlight that dehydration is preventable amongst older people. IMPLICATIONS: One in every 4 older adults has low-intake dehydration. As dehydration is serious and prevalent, research is needed to better understand drinking behaviour and assess effectiveness of drinking interventions for older people.
